How to check the connection state of BLE?

Hi,I'm using stm32wb55 for ble application.I want to check the connection state of BLE for conditioning case.Is there any global instance or register which contain the state of BLE?Thanks.

What is the STM32WL55 LDO mode output capacitor value on the VFBSMPS pin?

The datasheet indicates the value of 470nF for the SMPS mode on the VFBSMPS pin. But for the LDO mode, I didn't find the required value.Thanks

Hello guys,I want connect to a bluetooth device from STM32WB.I've used this function inspiered to setup the connection with the device found when scanning but it won't connect to it it always print out Connection To Slave Failed with reason 0x46 whic...

Why does aci_gap_set_discoverable() return Command Disallowed?

Under what circumstances will the BLE controller return Command Disallowed (0x0C)? I am calling aci_gap_set_discoverable() followed by aci_gap_update_adv_data() periodically. I see aci_gap_set_discoverable() return successful the first time that i...

Wait until BLE notification has been sent

I basically have this code:while (...) { // A while (BLE_STATUS_INSUFFICIENT_RESOURCES == aci_gatt_update_char_value(...)) { // B osDelay(10); } }   while (BLE_STATUS_INSUFFICIENT_RESOURCES == aci_gatt_update_char_value(...)) { // C osDelay...

IRQ handler not being called anymore after exit from low power mode (stop2) on the STM32WB55 Nucleo board

Could anyone please help me with this problem? Thanks in advance. I am using the low power manager (lpm) interface generated by MX for the STM32WB55 Nucleo board. I am using HSE as system clock source, so I did not make changes to the two functions P...
